The Ultimate Optical Illusion of Stereograms
A stereogram is an optical illusion of depth created from flat, two-dimensional image or images. Originally, stereogram referred to a pair of stereo images which could be viewed using stereoscope.
Stereograms were re-popularized by the creation of autostereogram on computers, where a 3D image is hidden in a single 2D image, until the viewer focuses the eyes correctly.
Autostereograms produce an illusion of depth using only a single image. The image is usually generated by computer by repeating a narrow pattern from left to right. By decoupling eye convergence from focusing operations, a viewer is able to trick the brain into seeing a 3D scene.
If a stereogram is viewed with the wrong method, the depth information is seen ‘backwards’; points intended to be in the background appear in the foreground and vice versa.

i just see normal pictures, they don’t move, there’s no 3D illusion, nothing, am i doing something wrong or is it because i use mac??
yes, it is because you’re using a mac…. people who have to use a mac because pcs exceed their abilities won’t be able to get their mind as far as to see such surreal things…
you are just not squinting at it the right way buddy…
Lol, I like the once with the naked women on them ^^
I am using my macbook air and I see everything all the 3D images. Maybe you need to try a little bit more.
